Ankle sprain is a highly observed injury in soccer due to repeated strenuous movements. Rehabilitation after leads decreased physical strength and muscle-joint function. The ankle sprained patients need improved specific fitness function simultaneously. Therefore, current study aimed compare high-intensity sports training (HISST) with interval (HIIT) identify effective for lower-extremity funct...

The effect of one-year physical training on heart rate variability in older adults was evaluated in 14 healthy men (age > 55 year). Measures of heart rate variability were obtained in both time and frequency domain. Tenminute ECG recordings were made in supine position and in standing position. A progressive climbing exertion test till exhaustion was performed to estimate maximal oxygen consump...

The purpose of this study was to examine the effects of a crossfit-based high-intensity power training (HIPT) program on aerobic fitness and body composition. Healthy subjects of both genders (23 men, 20 women) spanning all levels of aerobic fitness and body composition completed 10 weeks of HIPT consisting of lifts such as the squat, deadlift, clean, snatch, and overhead press performed as qui...

High-intensity interval training (HIIT) enhances skeletal muscle oxygen delivery and utilization but data are limited regarding fiber-specific adaptations in humans. We examined the effect of 18 sessions of HIIT (10 × 60-sec cycling intervals at ~90% HRmax , interspersed by 60-sec of recovery) over 6 weeks on markers of microvascular density and oxidative capacity in type I and II fibers in hea...

The purpose of the current study was to explore if training regimes utilizing diverse training intensity distributions result in different responses on neuromuscular status, anaerobic capacity/power and acute heart rate recovery (HRR) in well-trained endurance athletes. Methods: Thirty-six male (n = 33) and female (n = 3) runners, cyclists, triathletes and cross-country skiers [peak oxygen upta...

Background. There is sparse literature examining the ICB phase of aerobic- and anaerobic-trained athletes. Measurements of ICB phase values of athletes can help to evaluate the sport’s physiological demands and understand the physiological adaptations in response to physical training. Objectives. The purpose of this study was to examine the relationship between the isocapnic buffering (IC...

Ambrisentan in 22 patients with pulmonary hypertension diagnosed during exercise (ePH) improved pulmonary hemodynamics; however, there was only a trend toward increased maximum oxygen uptake (VO2max) secondary to decreased maximum exercise systemic oxygen extraction (Ca-vO2). We speculate that improved pulmonary hemodynamics at maximum exercise "unmasked" a pre-existing skeletal muscle abnormal...
